Introduction
xStatus ISDN BRI Interface [1..4] Layer2Alarm
Shows whether there are any alarms related to the data-link layer.
On: Layer 2 alarm.
Off: No alarm.
Value space of the result returned:
<On/Off>

xStatus ISDN BRI Interface [1..4] Channel [1..3] Type
Shows the channel type for a channel on a BRI interface. A BRI interface comprises two channels for
the primary communication and one channel for control and signalling information.
DChannel: The channel is a data channel (D channel), which carries the control and signalling
information in ISDN. The bit rate of the D channel of a BRI interface is 16 kbps.
BChannel: The channel is a bearer channel (B channel), which carries the primary video conference
or speech call communication in ISDN. The bit rate of a B channel on a BRI interface is 64 kbps.
Value space of the result returned:
<DChannel/BChannel>
Example:
xStatus ISDN BRI Interface 1 Channel 1 Type
*s ISDN BRI Interface 1 Channel 1 Type: BChannel

xCommand
Gives information about the call progress in a channel on a BRI interface. The information indicates
the various stages each channel goes through whilst establishing a connection.
Idle: The channel is idle. This state is normally only seen if the channel has never been used.
Calling: The network has acknowledged an incoming call, but the connection is not yet established.
Answering: The network has acknowledged an outgoing call, but the connection is not yet
established.
Connect: The connection is established.
Disconnecting: Waiting for the network to confirm the termination of the incoming or outgoing call.
Disconnected: The network has acknowledged the termination of the call. The channel is available for
a new call.
Value space of the result returned:
<Idle/Calling/Answering/Connect/Disconnecting/Disconnected>
Example:
xStatus ISDN BRI Interface 1 Channel 1 Status
*s ISDN BRI Interface 1 Channel 1 Status: Connect
** end
Shows the number calling into the ISDN BRI interface (for an incoming call), and the number that ISDN
Link is making a call to on the ISDN BRI interface (for an outgoing call).
Value space of the result returned:
<String>
Example:
xStatus ISDN BRI Interface 1 Channel 1 Call 30 CallingNumber
*s ISDN BRI Interface 1 Channel 1 Call 30 CallingNumber: "1234"
** end
Shows where the disconnection of a call on the BRI interface is originated. The location codes are
specified in ITU-T Recommendation Q.931 (the Cause information element).
Value space of the result returned:
<Integer>
Example:
xStatus ISDN BRI Interface 1 Channel 1 Call 30 CauseLocation
*s ISDN BRI Interface 1 Channel 1 Call 30 CauseLocation: 0
